Abstract: We present a comprehensive multi-wavelength study of the star-forming regionNGC 1893 to explore the effects of massive stars on low-mass star formation.Using near-infrared colours, slitless spectroscopy and narrow-band $H\alpha$photometry in the cluster region we have identified candidate young stellarobjects YSOs distributed in a pattern from the cluster to one of the nearbynebulae Sim 129. The $V, V-I$ colour-magnitude diagram of the YSOs indicatesthat majority of these objects have ages between 1 to 5 Myr. The spread in theages of the YSOs may indicate a non-coeval star formation in the cluster. Theslope of the KLF for the cluster is estimated to be $0.34\pm0.07$, which agreeswell with the average value $\sim 0.4$ reported for young clusters. For theentire observed mass range $0.6 < M-M \odot \le 17.7$ the value of the slope ofthe initial mass function, $`\Gamma$-, comes out to be $-1.27\pm0.08$, which isin agreement with the Salpeter value of -1.35 in the solar neighborhood.However, the value of $`\Gamma$- for PMS phase stars mass range $0.6
